International Pleuropulmonary Blastoma (PPB) Treatment and Biology Registry

Pleuropulmonary Blastoma Clinical Trial

Official title: International Pleuropulmonary Blastoma (PPB) Treatment and Biology Registry Protocol

Status Active, not recruiting

Clinical Trial Summary

Pleuropulmonary Blastoma (PPB) is very rare and there is no established "standard" or "best" therapy. For many years, children with PPB around the world have been treated according to decisions made case-by-case in many different hospitals by many different physicians. No treatment has been tested in a large group of PPB patients.

The goal is to treat many children with one treatment program and to learn the results of the treatment.

Clinical Trial Description

This Registry will collect family medical history and establishes a collection of specimens from PPB patients and their parents for future research. Primary goals of the biology research are (1) to identify new scientific ways to learn about PPB and the best way to treat it in the future and (2) to establish a collection of PPB biologic specimens for future research.

Background: PPB is a rare cancer of the lung presenting in early childhood, mostly from birth to age ~72 months. PPB occurs within the lung or between the lung and the chest wall. There are three forms of PPB called Types I, II, and III PPB. Children with Type I PPB require surgery and sometimes chemotherapy. Children with Types II and III PPB, require surgery, chemotherapy and sometimes radiation therapy. Because there has never been a consensus as to the best treatment for PPB, the Registry will provide treatment guidelines. It is the goal of the Treatment and Biology Registry that by offering specific regimens the Registry will be able to prospectively review and analyze the regimen for the first time.

Design:

• Diagnostic central pathology review will be required for patients who will be prospectively evaluated.

• This Treatment Registry will offer surgery and chemotherapy regimen guidelines, and optional radiation therapy guidelines for prospectively enrolled patients.

• The Treatment and Biology Registry will create a PPB biologic specimens reference bank for tumor.

Methods:

• For Type I PPB, surgery is necessary. Some doctors use chemotherapy after surgery. If chemotherapy is used the Registry will suggest that it be combination chemotherapy with vincristine, dactinomycin, cyclophosphamide (VAC ).

• For Types II and III PPB patients surgery is necessary, followed by chemotherapy. The Registry will suggest that subjects receive combination chemotherapy with Ifosphamide, Vincristine, Actinomycin-D and Doxorubicin (IVADo). Second look and possible 3rd look surgery may be required. Radiation therapy is recommended only for residual disease after maximum surgery.

Analysis: Statistical data analysis will include only centrally confirmed cases. Additionally only patients with PPB Type II or Type III who were enrolled and treated with IVADo as per the regimen will be compared to historical controls. No statistical analysis is planned for patients with Type I PPB. Future treatment will be compared to the IVADo regimen in order to measure improvements. ;
